Meningioma extracraneal en músculo temporal: Reporte de un caso

Extracranial meningiomas are rare tumors, accounting for approximately 1–2% of all meningiomas. Their location in the temporal region is exceptional and presents significant diagnostic challenges, as they can mimic other soft tissue neoplasms. Definitive diagnosis requires histopathological and immunohistochemical confirmation after complete resection, as percutaneous biopsy has limited utility. The differential diagnosis includes schwannoma, solitary fibrous tumor, soft tissue sarcomas, and reactive lesions, always considering the possibility of extension from an intracranial lesion or an ectopic primary origin. The prognosis is favorable after complete resection in low-grade tumors.
